Lack of silver chests

For some reason legendary rarity chests are far more common than epic rarity chests in thrax.
How bad? Gold chests went down all the way to sub 100k. Silver chests were under 15k on the auction house and now are above 500k with low quantity. There even are more platinum chest recipes than silver chests atm in cs.

I think if there would be more silver chests, the recipes would also be more valuable. Which would make more sense. Need a change that will lead into more supply of silver chests in my opinion.
